It fits the Sunseeker RMA1001M20V, RMA301M20V, RMA501M20V, and RMA801M20V cordless lawn mowers. Same voltage rail, same connector, same BMS communication protocol across all four models.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRMA Series compatibility:\u003c\/strong\u003e\n    All four RMA models share the same 20V battery platform, connector pinout, and BMS handshake. The mower deck and drive motor specs differ across the range, but the battery slot, discharge profile, and communication lines are identical — one battery fits all four.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through repeated blade-start cycles simulating thick-grass inrush current. The BMS held trip thresholds consistent with OEM spec and recovered cleanly after each high-draw pulse without locking out the pack.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal storage tip:\u003c\/strong\u003e\n    If the mower has sat unused since last season, check the pack voltage before charging. Cells that drop below 2.5V per cell over winter may not be accepted by the charger until a pre-charge recovery is attempted — most Sunseeker chargers show a fault light in this state. Charge indoors at room temperature before the first mow of the season.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff on thick-grass and wet-grass blade load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe blade motor on the RMA series draws a sharp inrush current every time it bites into dense or wet grass. If that spike exceeds the BMS overcurrent threshold — which sits lower on a warm or partially discharged pack — the BMS cuts power to protect the cells. The mower stops mid-row, then restarts once the BMS resets. Keeping the blade sharp reduces the motor load and lowers the inrush current on each cut pass, which keeps the BMS from tripping in the first place.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMower cuts out mid-row then recovers after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is thermal protection activating, not a dead battery. The BMS monitors cell temperature and shuts discharge when internal temps exceed the safe threshold — typically around 60°C at the cell wall. It clears automatically once the pack cools. If this happens consistently, allow a 5-minute cooldown between battery cycles and avoid mowing in direct midday sun where the pack surface temperature is already elevated before the cut begins.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381282013274,"sku":"BWCS-WRS300PX-1","price":76.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381282046042,"sku":"BWCS-WRS300PX-2","price":90.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381282078810,"sku":"BWCS-WRS300PX-3","price":101.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WRS300PX-1.webp?v=1778899919","url":"https:\/\/batteryweb.com\/products\/sunseeker-rma1001m20v-replacement-battery-20v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
